I'm in the habit of turning off the computer screen when listening during tracking, composing and mixing. In the past I've tried a big piece of thin cardboard on tape hinges, but that's a real pain. The problem with turning the screen on and off is the down time while waiting for it to re-initialize. I also have to wonder if I'm hastening its demise.

It would be wonderful if Reaper could hotkey-toggle the display on and off, or just fill it with non-illuminated pixels, or something equivalent.
